IntroductionThe use of radicals in organic synthesis continues to grow due to the myriad of advantages they offer over ‘traditional’ ionic reagents. This report collates a number of pertinent examples that highlight the synthetic potential of radical chemistry and is not a comprehensive overview. The report is organised in keeping with previous reviews by the author.1–4The popularity of radical chemistry is highlighted by the publication of an issue ofTetrahedrondedicated to radicals,5and a number of specialist reviews on the use of organocatalysis in enantioselective radical chemistry,6the applications of TEMPO in synthesis,7samarium(ii) iodide in asymmetric synthesis,8the effect of additives on samarium(ii) iodide,9the use of tris(trimethylsilyl)silane10and the chemistry ofN-,11P-12andS-centred radicals.13
